Is there any problem leaving roll paper loaded for extended periods of time?
Yes, according to Bill J: "I went away for about five days and left a roll of Canon Satin Photographic paper (7 mil, 190 gsm) loaded in the printer. I turned off the printer before I left. The first print I made after I came back showed four dents made by the rollers attached to the auto roll feeder unit, exactly 1 1/2 inches from the leading edge. I've also noticed some very shallow dents in the Canon Fine Art Bright White (20 mil, 330 gsm) after just a day or so of non-use. The light has to be at a very steep angle to see them, though. The printer was on, but sleeping, during this time. So, I recommend that you not leave roll paper loaded for very long, or at least plan on trimming off the first 1.5 inches (3.8 cm) if it's been a few days since you used the printer.
Gary Cay agrees: "I had a similiar problem, and even had the tech guy come out. He basically decided it is better to remove roll paper if not printing within about 24 hours because of the dents. Canon Support thought dents should not occur, but the tech did not know anything he could "fix" anything to make it different. So now I eject the roll when finished printing from roll or if turning off the printer overnight or longer. It is easy enough to insert the roll and get going again."
Others have reported no problems: John Hollenberg leaves a roll of Epson Premium Luster loaded all the time and may go weeks between prints. No problems noted.
